S500Q thiab S550Q yog cov qauv tsim rau siab -lub zog, quenched thiab tempered (Q + T) cov qauv steel phaj, feem ntau ua raws li cov qauv zoo li EN 10025-6, siv rau kev thov cov qauv welded / bolted xav tau zoo toughness thiab lub zog, nrog rau lub ntsiab lus 55 0'S' qhia qhov tsawg kawg nkaus tawm lub zog hauv MPa (500 N / mm² / 550 N / mm²), thiab 'Q' kos npe rau quenched & Tempered mob, feem ntau nrog qis - ntsuas qhov ntsuas kub. S550Q muaj lub zog siab dua S500Q, ua rau nws haum rau hnyav- cov ntawv thov uas muaj peev xwm thauj khoom yog qhov tseem ceeb.

Cov yam ntxwv tseem ceeb
Hom: High-yield- lub zog, quenched thiab tempered (Q + T) structural steel.
Txuj: Feem ntau raws li EN 10025-6 lossis ISO 630-4.
S (Structural): Qhia qhov tsim nyog rau kev siv cov qauv.
500/550 (Yield Strength): Yam tsawg kawg nkaus lub zog ntawm 500 MPa (N / mm²) rau S500Q, thiab 550 MPa rau S550Q.
Q (Quenched & Tempered): Cov hlau yog cua sov-kho (rhuab thiab txias sai, ces tempered) kom txhim khu lub zog thiab toughness.
Toughness: suav nrog qis- ntsuas qhov kub thiab txias (piv txwv li, -20 degree) rau kev ua haujlwm hauv qhov txias.
Daim ntawv thov
Cov choj, cov tsev, cranes, cov tshuab hnyav, thiab kev tsim kho loj.
Txhua qhov chaw siab zog - rau - qhov hnyav piv thiab weldability zoo yuav tsum tau.
